The AirTAC GFR60020LJF2TK AirTAC Filter Regulator NPT3/4 is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR60020LJF2TK is an AirTAC GFR filter regulator: one body that removes water and particulate from compressed air and then reduces and holds downstream pressure. This size 600 unit has 3/4 in NPT ports, a 40 um standard filter element and the default differential-pressure drain. The regulator is the low-pressure (L) type, the embedded square pressure gauge reads in psi, and a reverse (check) valve is fitted (code K). The bowl on this largest frame is aluminium alloy, no mounting bracket is included, maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, offered with manual, automatic or differential-pressure drains, 40 um or 5 um (W) elements, square or round gauges in MPa, psi or bar scales, G, NPT or PT threads, and bracket options. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and the datasheet for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Filtered, reduced-pressure air feeding a pneumatic stamping or forming press, where the low-pressure regulator type holds a gentler setting than a standard unit.
Conditioning the air feed to cylinder-driven packaging and cartoning machinery, removing water and particles before the air reaches valves and actuators.
A filtered, regulated drop at a maintenance bench supplying air tools and blow-off stations that run below normal line pressure.
Size 600 with 3/4 in NPT ports is the largest GFR frame; sizes 200, 300 and 400 step down for lighter duty - we can check the published flow curves against your air consumption before you order. Drain choice is differential-pressure (fitted here as the default), automatic (A) or manual (M); the element is 40 um standard with 5 um (W) available where finer filtration is needed. The gauge here is the embedded square type reading psi, and square or round gauges in MPa, psi or bar scales can be specified. Thread is NPT on this unit, with G (BSPP) and PT as order options, and the J code means no mounting bracket is included. The L code marks the low-pressure regulator type; its exact adjust range for this size is not published, so confirm it with us.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes filter-regulator flow as performance curves rather than a single rated figure, so we do not quote a number here. Send us your air consumption and line details and we will confirm the sizing and flow data from the datasheet before you order.
It marks the low-pressure regulator type. Standard GFR units adjust over the published standard range, while the L type is intended for reduced downstream pressures; the exact range for this size and type is not published, so ask us to confirm it for your setting.
